Phenomenon of declining anxiety sensitivity scores: a controlled investigation.
BACKGROUND
Repeated administration of anxiety sensitivity measures can often produce declining scores, even in ostensible control groups, which is a significant concern for researchers. The reasons for these changes are as yet unknown, but could be because of regression to the mean in samples selected on extreme scores, exposure to general information about anxiety contained in psychiatric interviews, or mere exposure to anxiety sensitivity information.


METHODS
This study sought to experimentally evaluate these potential explanations using a comprehensive measure of anxiety sensitivity and its subcomponents, a non-anxiety sensitivity measure (self-esteem), and participants representing the full spectrum of anxiety sensitivity.


RESULTS
Results indicated significant decreases in anxiety sensitivity scores (but not self-esteem scores) that could not be accounted for by regression to the mean or exposure to information about anxiety in general.


CONCLUSIONS
Several potential explanations for these findings are reviewed and implications for research study designs are discussed.
